Cosmic Velocity - Third
The third cosmic velocity is the minimum speed an object must reach to escape the gravitational pull of the Earth without further propulsion, approximately 11.2 km/s.
History/Origin
The concept of cosmic velocities was developed in the early 20th century to describe the different escape velocities from celestial bodies. The third cosmic velocity specifically relates to Earth's escape velocity, becoming prominent with advancements in astronautics and space exploration.
Current Use
The third cosmic velocity is used in space mission planning to determine the required speed for spacecraft to leave Earth's gravitational influence and reach interplanetary or interstellar space.
Velocity Of Light In Vacuum
The velocity of light in vacuum, denoted by the symbol c, is the constant speed at which electromagnetic waves propagate through empty space, approximately 299,792,458 meters per second.
History/Origin
The concept of the speed of light has been studied since the 17th century, with significant contributions from scientists like Ole Rømer, who first estimated its finite speed in 1676, and Albert Michelson, who refined measurements in the late 19th and early 20th centuries. The value of c was precisely defined in 1983 by the International System of Units (SI).
Current Use
The speed of light in vacuum is a fundamental constant used in physics, astronomy, and engineering. It underpins theories of relativity, defines the meter in the SI system, and is essential for calculations involving electromagnetic radiation and high-speed phenomena.
